Actions needed (Oct. 2017) Action Responsible The PS platform on ECAL must be rebuild and store in a safe place. General dimensions are reported in LHCb TC the calculation note stored in EDMS Refurbishing of minor parts of the PS platform LHCb TC supports. Investigate if the “floor above RICH 2” can be put in LHCb TC place with the “access tower” in position The C-Palonnier has to be refurbished. HSE have to HSE with LHCb perform a preliminary investigation TC Deadline/comments ~O K Spring 2018 By the final version By the final draft/refurbish on Spring 2018 (in case) Cradles for the Supermodules preliminary design: dismantling/transport/storage CALO/LAPP By the final draft/production drawings and Safety File for March 2018 Cradles for the lead preliminary design: dismantling/transport/storage CALO/LAPP By the final draft/ production drawings and Safety File for March 2018 The cradle for lead has to be refurbished. HSE have HSE with LHCb to perform a preliminary investigation TC Reverse engineering of the present cradle for lead By the final draft/refurbish on Spring 2018 (in case) LHCb TC The sections of plates of the floor for the access above the muon filters have to be retrieved and LHCb TC Pascal Perret - LPC Clermont stored in a safe 16/05/2018 place. ASAP Spring 2018 3

Actions needed (Oct. 2017) To To estimate the working area dose, the WPL should include in the WPP the number of person involved in the dismantling and the time person of work in the different zone closed to the detector. WPL By the final version The people involved in the activities have to be properly trained before that the activity starts. Identify the proper safety courses needed and report them in the WPP. A list of the courses offered at CERN can be found in the Training Catalogue. WPL with HSE/SEE By the final version Ensure that ECAL/HCAL can be moved according to the needs. LHCb TC By the final version The specific Work Package activities plan should be uploaded in the proper folder “Work Packages activities plan”. Include the crane needs.

Conclusion u A lot of activities to do in a short period n 3 weeks for preparation and electronics removal l n 9 + 1 (contingency) weeks for cables, detector and infrastructure l n u XCAL, M 1, RICH, (IT/OT - Sci. Fi? ) areas are affected 1 week for cables between CALO and patch panel behind M 5 Preparation (tools) is ongoing n n u Should be done in parallel with other activities A long way Almost in time Let’s hope for no bad surprises when the work will start … 16/05/2018 Pascal Perret - LPC Clermont 17
